Minella Rocco declared non-runner at Aintree Grand National

Top-weight Minella Rocco has been declared a non-runner in the Randox Health Grand National at Aintree on Saturday on account of the ground.

Jonjo O'Neill's charge filled the runner-up spot in last year's Cheltenham Gold Cup and pulled out of this year's renewal on the morning of the race due to the prevailing testing conditions at Prestbury Park.
